3. Chi-Square table p-values: use choice 8: χ2cdf ( The p-values for the χ2-table are found in a similar manner as with the t- table. The calculator will expect χ2cdf (loweround, upperbound, df). a. Left-tailed test (H1: σ < some number) Let our test statistic be χ2 =9.34 with n = 27 so df = 26. The p-value would be the area to the left of the test statistic or to the left o In our case, we used matrix A. For Expected, this can be any empty matrix (the calculator will automatically produce the expected values for us). In our case, we'll leave this as matrix B. Then, highlight Calculate and press Enter.
